We are planning to visit the San Juans mid-Sept. We will be arriving via Victoria BC (Sydney, actually) and returning thru Vancouver airport. Due to the limited ferries we will be flying by charter in and out of Friday Harbor. Questions: We want to avoid renting a car if possible so how much touring by bike, foot and ferry can we do over 4 days? Is Friday HArbour the most convenient place to stay or should we consider one of the other islands as our base? We hope to kayak, bike and hike. What are the must-see/must-do outdoor activities that do not include sitting in a motorized boat? Also need vegetarian-friendly restaurants. Prefer local ambiance..not touristy.
